North Charleston, SC: what's different here
North Charleston sits in Charleston County, about 6 miles and roughly 10 minutes by car from Charleston via the main highway. The city has many older homes with a mix of slab and crawl-space construction, which can affect where backflow devices are installed and accessed. North Charleston also hosts state backflow certification classes at the North Charleston Convention Center, with dates shown as June 9-12, 2026.
Who files a backflow test report in North Charleston?
The certified tester who performs the test submits the written report of inspection and testing results to the public water system. South Carolina requires all backflow testing to be done by a state certified backflow prevention tester. The tester holds an up-to-date certification card issued by the Department.
How often is backflow test report filing required?
Each backflow assembly must be tested after installation and before use by the customer. After that, assemblies must be tested at least once annually by a certified tester, unless a specific exception applies. Each test generates a report that must be filed.
What records must the water system keep?
Public water systems in South Carolina must maintain records of backflow assembly location, type, size, and annual testing results. Annual test reports must be submitted electronically through VEPO CrossConnex. The filing fee is $20.00 per test report.
